When the areas major agricultural product, hemp is making a comeback in the Altiplano section of Granada, Spain. Until the late nineteen sixties industrial hemp growing formed the backbone of the wholly agricultural section of Spain. Towards the finish of the Franco era, with the invention of nylon and the mechanisation of agriculture the majority of the population was forced off the land to get focus on the coast and major cities.
With the advent of the eco-age the interest in industrial hemp has been revived as it is a major constituent of eco-bricks, an important element of sustainable housing.
Hemp arises from the Anglo Saxon word’haemp’and is the popular name for plants of the cannabis genus. Hemp usually refers to the strains of the plant cultivated exclusively for industrial use as opposed to cannabis which will be related to pot and similar drugs.
Hemp features a huge number of uses but continues to be overshadowed by the cannabis connotation of illegal drugs, with which it’s often confused. However hemp can legally be grown, under licence, in lots of countries, including the European Union countries and Canada.
Cannabis sativa L. may be the variety primarily grown for industrial purposes, it is a fast growing plant and has been cultivated for many thousand of years being used to make rope, clothing, paper, hemp oil and medicines. Growing hemp improves the problem of the ground and reduces ambient contamination. It’s a robust plant that will require neither herbicides nor pesticides during its cultivation.
Hemp as an industrial material features a ten thousand year history. The first recorded utilization of hemp was as a material fabric, within China as far back as 8000BC.C. Circa 4000B.C. hemp started to be used, again in China, to make ropes and as food. 2000 years later, the Chinese hemp oils and medicine were in use. By 1000B.C. its use had spread to India and Greece where the initial instances of hemp paper were found.
By the 6th century hemp was being used in Europe in certain amazing ways, in France a hemp reinforced bridge was built and it’s still being used today. The hemp fibre also found uses in sailmaking, caulking materials, fishing nets and lines. In later years hemp was used to make many different foodstuffs including butter and beer. By the 15th century Renaissance painters were utilizing hemp canvases.
Today industrial hemp is used to create a staggering number of products including medicines, body maintenance systems, building and insulating materials, clothing, textiles, food, fuel, livestock food and bedding, plastics and paper.
In the building industry hemp bricks, because of their sustainability and excellent insulation properties, are increasingly being used to make external and internal walls of ecological homes. Of this type of Spain the external walls of an eco house will include a eco-bricks, stated in Guadix with the proprietary name of Cannabric® ;.
Cannabric® derives its properties from industrial hemp fibres (cáñamo). The hemp bricks are composed of industrial hemp fibres, slaked lime and a combination of innert mineral materials. The bricks combine the functions of a lot bearing wall that is fire-resistant and doesn’t require the addition of thermal or acoustic insulation. kratom for depression
The most important element of the eco-brick is industrial hemp that includes a very low thermal conductivity (0.048W/m²k) producing a brick with vastly superior insulation properties against both cold and heat. The mineral element of the bricks gives them their mechanical strength. Being fully a solid brick, with a higher specific heat, it’s the optimal thermal properties to guard against heat.
